Boundary Scan: Test More, Pay Less

Today's test engineer is faced with a multitude of test technologies. The most common and best known test technologies are divided into two groups: optical and electrical.
How Flying Probers Optimize Test Strategy

Manufacturers are constantly looking for ways to maximize the use of the equipment on their manufacturing floor. Resources are limited, time is precious and traditional testing is being challenged by new technologies that continue the push to design with smaller components.
Boundary-Scan: The Technology Has Grown Up

Boundary-scan PCB testing has come of age largely because of easy-to-use and highly automated tools for developing boundary-scan tests. In addition, a newer range of low-cost or even no-cost test utilities have made this technology even more accessible. As a bonus, today's JTAG is also ...
New Test for Pad Cratering

A common failure mode in lead-free assemblies is pad cratering, where the contact pad on a printed circuit board or package substrate lifts away from the surface. There are many factors that cause this failure mode to be more prevalent in lead-free assemblies compared to tin-lead assemblies ...
How AOI Ensures Conformal Coating is Working

Everyday electronic devices such as mobile phone handsets are increasingly expected to withstand environmental stress while offering greater quality and longer lifetime; attributes that can be enhanced by conformally coating selected areas of their PCBs. In safety related electronics ...
